Comparison
Formspree alternative
Formspree is a solid form backend with paid plans starting around $10–15/mo for a few hundred submissions. Plinth Forms targets the same job with an open-source screener, anonymous minting for first success, and Polar MoR billing. Free quota is intentionally usable; Pro is $19/mo with webhooks and higher limits.
